Analisis dan Optimalisasi Potensi Lahan Pertanian Sebagai Kajian Dampak Positif Erupsi Gunungapi Kelud 2014

Abstract

Abstrak Erupsi gunungapi Kelud pada tahun 2014 membawa dampak yang beragam terhadap kondisi pertanian di sekitarnya. Selain dampak negatif, erupsi gunungapi Kelud membawa dampak positif khususnya pada potensi lahan terdampak yang perlu dioptimalkan. Melalui penelitian ini, kajian optimalisasi potensi lahan terdampak erupsi dilakukan dengan beberapa tahapan. Tahap pertama berupa analisis kesesuaian lahan melalui penilaian multikriteria dan teknologi Sistem Informasi geografis (SIG). Selain kajian fisik, kegiatan Focus Group Discussion (FGD) merupakan tahapan kedua yang dilakukan untuk mengetahui bagaimana persepsi masyarakat terkait dengan dampak erupsi Gunungapi Kelud. Hasil penelitian menghasilkan peta kesesuaian dengan kelas kesesuaian S1 (64,74%), S2 (31,51%), S3 (3,75%). Berdasarkan hasil pemetaan ini, sebagian besar wilayah Gunungapi Kelud berpotensi untuk pengembangan pertanian. Hal ini didukung dengan persepsi masyarakat kawasan Gunungapi Kelud yang berpendapat bahwa dampak positif erupsi dirasakan secara signifikan. (FGD) was performed in the second step to identify the community's perception of the eruption impact. The research produced land suitability maps consisting of the following classification: S1 (64.74%), S2 (31.51%), and S3 (3.75%). The maps revealed that the majority of the land in Kelud Volcano had the potentials for agricultural development. These findings were supported by the perception of the local community, which argued that they could significantly benefit from the positive impact of the eruption. Kata kunci: Gunungapi Kelud, dampak positif, kesesuaian lahan Abstrac T.The 2014 eruption of Kelud Volcano has brought various effects on the surrounding agriculture. Aside from negative impact, it affected the potentials of agricultural land positively. This research analyzed the optimization of eruption-affected land using several steps. The first step was land suitability analysis with multicriteria assessment and Geographic Information System (GIS) technology. In addition to the physical analysis, Focus Group Discussion

FOSS (Free Open Source Software) Integration to Implement WebGIS-Based Information System of Kelud Volcano

“…Kelud Volcano has a high potential for landslide hazards due to the accumulation of material from the eruption in 2014. Based on the results of landslide vulnerability mapping that uses GIS (Geographic Information System) and FAHP (Fuzzy-Analytical Hierarchy Process) integration methods, Kelud Volcano area is categorized in high vulnerability zone landslide hazard (35.77%) and very high vulnerability zone (44.29%) of the total research area of 271.21 km 2 [3]. Volcanic characteristics not only have a negative impact or harm humans in the short term but also have a positive impact or benefit humans in the long run [4].…”

“…Volcanic characteristics not only have a negative impact or harm humans in the short term but also have a positive impact or benefit humans in the long run [4]. Land suitability on the western slopes of Kelud Volcano using the AHP method is dominated by the category of S1/very suitable (64.74%) and the other S2/quite appropriate (31.51%), and S3/marginal according (3.75%), of the total area of 240.86 km 2 [3]. The impact of post-eruption Kelud Volcano also encourages the development of mining, tourism, and agriculture sectors as the capital for regional development .…”
